Is anyone else still having this issue? I'm on 23.7.4 and it was an issue with 23.7.3 as well.
My WAN is pppoe and I get a /56 off my ISP via DHCPv6. I hand out ipv6 to my LAN via RA unmanaged (SLAAC - no DHCPv6). On a reboot my network clients don't get anything ipv6 related. Log in, restart RA and straight away they get what they need and everything works.
How best to diagnose this? My gut feel is that RA is trying to start too early and perhaps it needs to wait until the WAN has ipv6 details from ISP?
Can you post contents of /var/etc/radvd.conf after boot?
It doesn't appear to be a general issue anymore.
Cheers,

Here you go, I've redacted some of the addresses, definitely an issue for me
# Automatically generated, do not edit
# Generated RADVD config for manual assignment on lan
interface igc1 {
AdvSendAdvert on;
MinRtrAdvInterval 200;
MaxRtrAdvInterval 600;
AdvLinkMTU 1492;
AdvDefaultPreference medium;
prefix 2a00:<redacted>::/64 {
DeprecatePrefix on;
AdvOnLink on;
AdvAutonomous on;
};
RDNSS 2a07:<redacted> {
};
DNSSL home.arpa {
};
};
# Generated RADVD config for manual assignment on opt1
interface vlan01 {
AdvSendAdvert on;
MinRtrAdvInterval 200;
MaxRtrAdvInterval 600;
AdvLinkMTU 1492;
AdvDefaultPreference medium;
prefix 2a00:<redacted>/64 {
DeprecatePrefix on;
AdvOnLink on;
AdvAutonomous on;
};
RDNSS 2620:fe::fe 2606:4700:4700::1112 {
};
DNSSL home.arpa {
};
};
This is right after reboot when the service is stopped?
If yes when you restart the service the config doesn't change and it's up and running?
# pluginctl -s radvd start
(check config for differences)
Cheers,
Franco
Ah no sorry that's when I've restarted it. I'll repost shortly
This is straight after a reboot, before I manually restart RA. There's no prefix section?:
# Automatically generated, do not edit
# Generated RADVD config for manual assignment on lan
interface igc1 {
AdvSendAdvert on;
MinRtrAdvInterval 200;
MaxRtrAdvInterval 600;
AdvLinkMTU 1500;
AdvDefaultPreference medium;
RDNSS 2a07<redacted> 2a07<redacted> {
};
DNSSL home.arpa {
};
};
# Generated RADVD config for manual assignment on opt1
interface vlan01 {
AdvSendAdvert on;
MinRtrAdvInterval 200;
MaxRtrAdvInterval 600;
AdvLinkMTU 1500;
AdvDefaultPreference medium;
RDNSS 2620:fe::fe 2606:4700:4700::1112 {
};
DNSSL home.arpa {
};
};
The fun part is radvd should restart when the prefix is available. :)
System log may give more clues.
Cheers,
Franco
OK here you go, it looks to me like RA is starting too early and not waiting for WAN to be fully configured by ISP?

Oh great, it's PPPoE. I missed this earlier. Can you try to set a new GUI tunable "net.inet6.ip6.dad_count" with value "10" and see if that helps with the reboot behaviour?
Cheers,
Franco
No, still getting:
Error dhcp6c transmit failed: Can't assign requested address
Notice dhcp6c RTSOLD script - Sending SIGHUP to dhcp6c
Notice dhcp6c dhcp6c_script: REQUEST on pppoe0 executing
Notice dhcp6c dhcp6c_script: REQUEST on pppoe0 renewal
Notice opnsense /usr/local/etc/rc.newwanipv6: Failed to detect IP for interface wan
And then if I manually restart RA I don't get anything to begin with, then maybe 30-60s later it works, not sure if that's a coincidence or not.
What is that parameter designed to do, and is the "10" a delay of some kind?
Tried rebooting again, and not manually restarting RA so soon. Still nothing after 5 min, last 2 lines in log:
2023-09-15T10:04:01 Notice opnsense /usr/local/etc/rc.newwanipv6: Failed to detect IP for interface wan
2023-09-15T10:04:05 Notice kernel <7>cannot forward src fe80:2::<redacted>, dst 2a00:<redacted>, nxt 6, rcvif igc1, outif pppoe0
Only get ipv6 on LAN after manually restarting RA.
Yes it's broken. I have not found out why yet.
> /usr/local/etc/rc.newwanipv6: Failed to detect IP for interface wan
PPPoE restarts right after acquiring the IPv6 address leaving IPv6 stranded.

Franco
OK let me know if I can be of any help in debugging this. pppoe is still very popular in the UK and Europe (unfortunately) so there must be many people with this problem. I've seen a few posts on reddit over the last few months.
I also raised a github issue yesterday (is that appropriate?) here: https://github.com/opnsense/core/issues/6850 but it's not been picked up yet.
It says page not found?
I think it's tracked over here https://github.com/opnsense/core/issues/6671
Cheers,
Franco
I reckon you have "Use IPv4 connectivity" set for your DHCPv6 mode in WAN interface?
Cheers,
Franco
Under WAN interface, ipv4 is set to PPPoE and ipv6 is set to DHCPv6. Under LAN I have ipv4 set to to static ipv4 and ipv6 set to track interface.
re github, it's weird as I can access the issue I raised via one browser (brave) but not another (firefox).
I'll subscribe to #6671, should I add my logs to that?
Also, do you have intrusion detection or zenarmor running?
No nothing like that, fairly simple setup
If you could mail them that would be helpful. Details in second to last comment.
Cheers,
Franco
OK done, I'm known as "AltyCoder" on github.
Let me know what else I can do to help diagnose. I wish ISPs would ditch pppoe as it's seems unnecessary when we can switch out our routers and get a connection with simple credentials!
